Background and Aim: This study aimed to assess the prevalence and severity of temporomandibular disorders (TMDs) among 1533 dental students at a Turkish State University using Fonseca’s Anamnestic Index (FAI). It also examined the association of TMD symptoms with gender and academic year to support early recognition and awareness of TMDs in dental students. Materials and Methods: A total of 1533 dental students were asked to fill out Fonseca’s questionnaire. The results were analyzed for students from first grade to fifth grade, and the percentage values were compared between males and females, across different levels of education and presence of TMDs. Results: The overall prevalence of TMD was 58.6%. Females were more affected (62.6%) than males (37.4%). TMD prevalence increased progressively across academic years: first-year (36.7%), second-year (46%), third-year (65.5%), fourth-year (79.6%), and fifth-year (82.3%) (p<0.001). Among students with TMD, 73% of females and 66.8% of males described themselves as tense; 74.5% of females reported neck pain. Females had higher risks of headache (OR=1.566, p<0.001) and awareness of limited mouth opening (OR=1.677). Conclusion: TMD symptoms were commonly observed among Turkish dental students, particularly in females and those in advanced academic years, potentially reflecting cumulative psychosocial stress and functional strain. These findings underscore the importance of early identification and incorporation of preventive measures into dental education to minimize the risk of long-term orofacial dysfunction.
